ChuChu ChuChu Nipple for paper packs, drinkable anywhere, anytime ※Sterilized ⚫︎Product Description This is a nipple specifically designed for baby drinks in paper packs, allowing for immediate feeding anywhere. You can attach it to the paper pack and feed your baby without transferring the drink to a bottle. The nipple is modeled after a mother's breast, controlling the flow of liquid according to the baby's sucking strength, making it suitable for newborns to weaning. It can be used regardless of age, providing peace of mind during emergencies. ⚫︎I purchased a large quantity, and I am selling this one as I have used it a few times and no longer plan to use it. Please refrain from purchasing if you are overly concerned about the condition.
